RUBBER-TREAD HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 644,879, dated March 6, 1900. Application filed January 2, 1900. Serial No. 72. (No model.)

To all wh/0m, it may con/067471.:

Be it known that we, WILLIAM P. STRAW- MYER and OTTO NILIUs', citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in I-Iorseshoes, of which the following is a speciiication.

` Our invention relates to that class of horse- I place and given the requisite strength and proportion, all as will be'hereinafter more particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, Figure l is an upperside plan view of a horseshoeV embodying our said invention; Fig. 2, an under side plan view showing that surface which comes in contact with the ground, a part of the outer metal portion being broken away; Fig. 3, a view in the same position as Fig. 2 with the cuter metal and rubberportions removed, showing a plan view of the inner metal and leather portions 5 Fig. 4, a vertical sectional view as seen from the dotted line 1i 4 in Fig. 2, and Fig. 5 a detail sectional vertical view as seen from the dotted line 5 5 in Fig. 2.

Our improved shoe is composed of four principal parts. The part A, which comes in contact with the horses hoof, is preferably formed of sole-leather. Upon this is preferably a sheet-metal stiffening plate or spring B. Secured to the leather portion A and covering the plate or spring B is a part C, of yielding material, preferably rubber. Outside and inclosing a considerable portion of the part C is a metal part D, which in many respects compares in shape and character with the major portion of an ordinary horseshoe.

The parts A and B are first preferably riveted together by rivet-s r. The part Aforms a complete base for the shoe structure upon which the others parts are placed in building vof an ordinary horseshoe.

the shoe. The part B is comparatively narrow for the greater portion of its length, but at the ends, immediately within the heel. portions, it is enlarged or widened out for the purpose of giving strength and stiffness at this point, over which the outer part D is not intended to extend.

The part C is of a peculiar form. It is, generally speaking, of substantially the'shape Its rear or heels are raised or thickened, as at c, so that they extend above or beyond the outer metal portion D when the parts are assembled and come in immediate contact with the ground. Around the outer rim of this rubber portion is a flange f, which is formed integrally therewith., and its inner side is beveled or also somewhat iiange-like in form. This is to provide a convenient and efficient means of atL tachment between the leather portion A. and this rubber portion O, which attachment is effected by a row of stitching s, which extends around the outer edge through the flange f, and thence around the ends and inner edge, as shown. This part C has a recess and incloses the part B.

The outer metal portion D, as before stated, is in its general form much the shape of an ordinary horseshoe. It is placed around the outer edge and .upon the outer side of the structure,- covering the flange f of the rubber and protecting its outer edge. At its rear ends it extends up slightly onto the heel p0rtion of the rubber part, said heel portion being for this purpose given a roof-like form at this point, as best' shown in Fig. 5, and this metal part being formed correspondingly to lit onto the corresponding faces of said heel portions. As will also be observed, especially in said Fig. 5, the outer metal portion at this point'slightl y overlaps the stiffer widened or strengthened rear ends of the metal part B, so that although the rubber is exposed and comes in contact with the surface over which the horse is traveling it is still rigidly and strongly supported. Having thus fully described oursaid invention, whatwe claim as new, and desire to secure by Letters Patent, is-

. l. A horseshoe composed of an inner nonmetal part, which bears against the horses hoof when in position, a stiening part B secured thereto, a non-metal adhesive part O having a flange f, and an outer metal part placed upon the said ilange and thus gripping and holding said non-metal part.

2. The combination, in a horseshoe, of a leather part A, a metal stiffening part B se.- cured thereto having enlarged rear ends, a rubber part C secured thereon and having heel portions With outer inclined surfaces, and an outer metal portion D having its rear ends formed to fit up onto the inclined heel portions of the rubber part C, said parts being so ar; ranged that the heel portions of the rubber part are supported. and strengthened by the part B so far as they proj eet beyond said part D, substantially as shown and described.

3. The combination, in a horseshoe, of the sole-leather, part A of substantially the form of the horses hoof, a reinforein narrow metal 1 tially as show n and described.

In witness whereof We have hereunto set ourhands and seals, at Indianapolis, Indiana,I this 30th day of December, A. D. 1899.
